which of the following is a true metric conversion factor?
1000mm = 1m
1m = 1000 km
1mm = 1000m
100m = 1cm

Explanation:

Step1: Recall metric - length conversion

In the metric system, 1 kilometer (km) = 1000 meters (m), 1 meter (m)=10 decimeters (dm), 1 decimeter (dm) = 10 centimeters (cm), 1 centimeter (cm)=10 millimeters (mm). So 1 m = 100 cm=1000 mm.

Step2: Analyze each option

• Option 1: Since 1 m = 1000 mm, this is a correct conversion.
• Option 2: 1 km = 1000 m, not 1 m = 1000 km.
• Option 3: 1 m = 1000 mm, not 1 mm = 1000 m.
• Option 4: 1 m = 100 cm, not 100 m = 1 cm.

Answer:

1000mm = 1m
